## What reviewers say

**Evap40 Evaporative Humidifier** — Only one whitelisted tester (Reviewed/USA Today) covers the exact Vornado Evap40, and it curated the pick from user reviews and product specifications rather than hands-on lab-testing this model, so no measured data exists for it. Reviewed praises the long runtime (fewer refills), quiet operation, and spill/leak-proof build, but flags the high price. Treat as light, single-source evidence. (1 sourced review.)
